Drawing -- what it is and what it means -- links four very different shows of contemporary art that opened in London this September. First is the Berlin-based Portuguese artist Jorge Queiroz, who fills Thomas Dane Gallery in St James with five large and 40 smaller works on paper in gouache, pencil, ink and oil stick that nudge abstraction towards figuration in a way reminiscent of drawings by Roberto Matta and Arshile Gorky.
